NONGLARE SHIELD FOR HEADLIGHTS Filed D60. 31, 1927 w, l///////// g/ a K1 i i i Patented Dec. 17, 1929 UNITED STATES PATENT OFFICE NONGLARESHIELD FOR HEADLIGHTS Application filed December 31, 1927. Serial No.243,883.

This invention relates to those devices which are adapted to be appliedto the headlight of an automobile, to the rear of the lens and in thelower part thereof, for the purpose of obstructing, or so deflecting,the rays of light from the lower part of the reflector that glare willbe prevented.

The object of the invention is to provide a simple, inexpensive, lightand durable nonglare shield of this general character which will embodyimprovements whereby it may be secured in position by the headlight bulbalone, or, if the type so requires, be secured by the electric bulb andthe rim of the headlight, without necessitating the use of screws,

bolts, or other fastening devices.

The present non-glare shield is made from a single piece of sheetmaterial, either of cloth, paper, fiber, composition, or metal.

Preferably, aluminum will be used because of its strength and lightnessbut I do not limit the invention in that respect.

The shield may be imperforate, except at its ends where it is providedwith holes for its attachment, or it may have a considerable number ofperforations, serving to allow some of the rays of light to pass throughand to prevent overheating.

In the following description, and in the drawings, disclosure is made ofthe two forms the shield may assume, according to the type of lamp onwhich it is used but the blank from which the shield is made is the samein both instances, the different shapes resulting from bending the blankso that it will be solely held by the lamp, or, on the other hand, bearranged with its ends in engagement with the lamp and with the rim ofthe headlight.

In the accompanying drawings:

Figure 1, is a vertical section through an automobile headlight, showingone way in which the shield may be arranged;

Fig. 2, is a similar view showing another manner of arranging theshield;

Fig. 3, is a front elevation, the shield being arranged as shown in Fig.1;

Fig. 4, is a face view of the blank, dotted lines showing the creasewhere the blank may be folded or bent to assume either of the.

forms shown in Figs. 1 or .2; and

Fig. 5, is a similar view illustrating the use of perforations in theshield.

The blank from which the shield is made, whether of cloth, paper, fiber,composition, or metal, is originally of the shape shown in Fig. 4, beingprovided with a body 1 of more or less sector-shape and a neck or stem2. The neck and the end of the body 1 are provided with holes 3, 4,respectively, said holes being of a size adapting them to receive theneck of the usual headlight electric bulb 5 so that when the bulb issecured in its socket 6, one, or both ends of the shield may beanchored, according to the type of lamp 7, 8, Figs. 1 and 2, on whichthe shield is used.

The body 1 maybe imperforate, as shown in Figs. 1 to 4 or it may beprovided with a considerable number of perforations 9 as shown in Fig.5.

According to the type of lamp, and, more particularly, the shape of thereflector 10, 11, thereof, the shield will be secured by the bulb 5 atone end and by the lens ring 12 at its lower end as shown in Figs. 1, 3,or, both ends of the shield will be secured by the lamp as shown in Fig.2. l/Vith that end in view, the shield is provided with a transversecrease 13 extending across the body 1 so that a well defined angle orhorizontal ridge 14 will appear just back of the lens 15 when the shieldis arranged as shown in Fig. 1 or as in Fig. 2.

In each instance the shield is in more or less folded condition, thefold being defined by the crease 13 and ridge 14.

lVhether the shell be used as shown in Fig. 1 or in Fig. 2, there isprovided a horizontally disposed part 16 below the bulb 5 which cuts offthose rays of light which cause a headlight to exhibit glare to a driveror person in front of the headlight.

According to the type of headlight, the shield may be arranged in eitherof the two ways illustrated in Figs. 1 and 2. When it is arranged asshown in Fig. 2, the neck of the bulb 5 will pass through both of theholes 3, 4. WVhen the shield is arranged as in Fig. 1, the neck of thebulb 5 will only pass. through hole 4, the neck 2 having the hole3,-th.en being bent as shown at 17 and clamped between the shell of theheadlight and the rim 12.

The material of which the shield will be made, will have such stiffness,although of inherent flexibility, that it will retain itself in positionwithout requiring fastenings of any character.

I am aware that the invention is susceptible of modification; therefore,I do not limit myself to the specific embodiments disclosed, except asstated in the'elaimsv l What I claim is: I

1. An attachable and detachable non gl-are V shield for automobileheadlights, comprising a single strip of flat material bent or foldedintermediate its ends to provide'an upper part which is concaved onits-upper, face so that said facewill throwtherays oflight upwardlyagainst the upper part of the headlight reflector when the shield is inposition on the. headlight, and a lower part joined to the front edge ofthe upper partfalong. the

line on which the strip is bent, or fo1ded ,"the opposite. ends of saidshield being formed for engagement by the headlight itself with;

out requiring special fastening means, when the-shield is in positioninia headlight, v

2. The combination with the reflector and lamp of a headlight, of anattachable and de tacha'ble non-glare shield comprising a single stripof flat material bent or folded intermediate its ends toprovide anupper. part;

' which is arranged in general lateral position below the lampandadapted ttithrow the rays of light upwardly against the upper part of.the headlight reflector, and a lower part joined toithe front edge oftheupperpart along the line on which the strip is bent or folded, both endsof said shield being formed so that the shield is engaged and held bythe headlight itself withoiltrequiring special fastening means.

In testimony whereof I aflix my signature.
